EulerOS 2.0 SP1 : kernel (EulerOS-SA-2016-1020)

Synopsis :

The remote EulerOS host is missing multiple security updates.

Description :

According to the versions of the kernel packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

- A race condition flaw was found in the way the Linux
kernel's SCTP implementation handled sctp_accept()
during the processing of heartbeat timeout events. A
remote attacker could use this flaw to prevent further
connections to be accepted by the SCTP server running
on the system, resulting in a denial of
service.(CVE-2015-8767)

- The ovl_setattr function in fs/overlayfs/inode.c in the
Linux kernel through 4.3.3 attempts to merge distinct
setattr operations, which allows local users to bypass
intended access restrictions and modify the attributes
of arbitrary overlay files via a crafted
application.(CVE-2015-8660)

- Several Moderate and Low impact security issues were
found in the Linux kernel. Space precludes documenting
each of these issues in this advisory. Refer to the CVE
links in the References section for a description of
each of these vulnerabilities. (CVE-2015-8746,
CVE-2015-8812, CVE-2016-2069, CVE-2016-2117,
CVE-2016-2384, CVE-2016-2847)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
